As a matter of trivia, the only official members of The Allman Brothers Band were Gregg, Dickey, Butch, and Jaimoe. Derek and Warren and Allen and Marc and anyone else were always contract players, they got union scale per week for the first several years and eventually negotiated better pay, but not official membership.

Even Toler Brothers were not ever official members. Or Chuck Levell.

Neither Gregg or Dickey was about to give royalties to guys that weren't even born when they were writing the good stuff.
